82 LIST OF FLIES. 
Black ant flies.— Numbers struggling on spider webs wove 
in the angles of posts and rails by the water sides, where 
numbers of the larger, as well as the smallest flies of the 
day, are held fast in their fine fibred toils. Ambry at the 
feet and end of body. 
ed ant fly.—Took one off a spider’s web at Robin Hood, 
which sparkled in the sun with fire and gold, and of a dull 
amber transparency. Full length, near three-eighths ; wings 
an amber tinge. 
Red dun. Full length, three-quarters; length, half an 
inch ; feelers, half an inch. Altogether of a dullish red or 
ambry hue; upper parts a shade darker. Body nearly 
cylindrical, with a few short hairs round the last joint ; top 
wings slightly broken with veins and faint freckles ; under 
wings thin and uniform, of a light shade of amber when 
looked through to the light, a red ambry tinge altogether. 
This fly was hatched in a water pot. The creeper was put 
in in May or June, and soon after fastened itself to the 
side, near the bottom, and was hatched on the 18th inst. 
The pot stood in the garden, and the fly was found float- 
ing on the water, alive and perfect, with its empty creeper 
skin beside it, and its empty artificial case fast to its original 
place. The pot was covered with a piece of gauze, fastened 
to a wire hoop, to prevent escape. 
Late black gnat.—Out in the daytime. 
Note ror Aucust.—The change of temperature of the 
air begins to tell on insects this month, and swarms of the 
tender tribes are swept off, but the waters continue full of 
creepers, the constant breeders are unimpaired, and the sec- 
ond swarms of some are turning out more numerous than 
the first. The extracts for the month are taken from notes 
made on fishing days and other times of research and obser- 
vation, during the seasons of many years, which, after num- 
berless close examinations and corrections, formed the foun- 
dation of the list of flies. The aquatic flies mentioned in them
